Cannot execute ArduCAM_Host_V2.0_Mac under macOS Big Sur v11.6 (Intel)

Attempting to execute ArduCAM_Host_V2.0_Mac under macOS Big Sur v11.6 (Intel) fails with the message:

You do not have permission to open the application “ArduCAM_Host_V2.0_Mac”.

I suspect that this is a codesign issue.

codesign -d reports that: code object is not signed at all

Attempting to sign the app with “codesign --force --deep --sign - /ArduCAM_Host_V2.0_Mac.app” results in the message:

unsealed contents present in the bundle root

Anyone else have this problem or suggestion on how to resolve?

Kind regards.

Have logged this as issue #537
